AWS OpsWorks extraits de modèles

AWS OpsWorks est un service de gestion d'applications qui simplifie un large éventail de tâches telles que la configuration logicielle, le déploiement d'applications, le dimensionnement et la surveillance. AWS CloudFormation est un service de gestion des ressources que vous pouvez utiliser pour gérer AWS OpsWorks des ressources, telles que des AWS OpsWorks piles, des couches, des applications et des instances.

AWS OpsWorks exemple d'application PHP

L'exemple de modèle suivant déploie un exemple d'application Web AWS OpsWorks PHP stocké dans un dépôt Git public. La AWS OpsWorks pile comprend deux serveurs d'applications dotés d'un équilibreur de charge qui répartit le trafic entrant de manière uniforme sur les serveurs. La AWS OpsWorks pile inclut également un serveur de base de données MySQL principal pour stocker les données. Pour plus d'informations sur l'exemple application AWS OpsWorks , veuillez consulter la rubrique Procédure de création d'une pile de serveur d'application pour découvrir les concepts de base d' AWSAWS OpsWorks dans le Guide de l'utilisateur AWS OpsWorks .

Note

Les DefaultInstanceProfileArn propriétés ServiceRoleArn et font référence aux rôles IAM créés après votre première utilisation AWS OpsWorks .

L’exemple définit le paramètre MysqlRootPassword avec sa propriété NoEcho définie sur true. Si vous définissez l'NoEchoattribut surtrue, CloudFormation renvoie la valeur du paramètre masquée par des astérisques (*****) pour tous les appels décrivant la pile ou les événements de la pile.

Important

Plutôt que d'intégrer des informations sensibles directement dans vos CloudFormation modèles, nous vous recommandons d'utiliser des paramètres dynamiques dans le modèle de pile pour référencer les informations sensibles stockées et gérées à l'extérieur CloudFormation, par exemple dans le AWS Systems Manager Parameter Store ou AWS Secrets Manager.
